Velox Blister of 2 threaded co2 cartridges

The CO2 refill cartridge is the ideal ally to re-inflate your tube or your hose. Designed to make re-inflation easier, this accessory is equally at home on a road bike, mountain bike, city bike or ebike. The CO2 refill cartridge contains air suitable for the pressure required by all bicycle tires. Tubeless tires are inflated to 2.5/3.0 bar for mountain bikes and 7/9 bar for road bikes depending on the tube diameter. A CO2 refill cartridge is used only once. To avoid the impact of the cooling on the hands, it is recommended to take the cartridge by the protection label or with a glove when using it.
